“…However, as studies indicate, the transition to renewable energy is currently a major challenge. It cannot be met effectively without understanding the factors that underlie such a transition [3]. Based on a study of renewable energy consumption in the Eurozone in the years 2000-2019, the authors of [3] showed a significant relationship between renewable energy consumption and the amount of electricity generation and energy production by other sources.…”

The paper presents a proposal for an in-house mathematical model of a liquid flat-plate solar collector. The proposed model is a one-dimensional distributed parameter model enabling simulations of the collector operation under arbitrarily variable boundary conditions. The model is based on the solution of energy balance equations for all components of the collector. The formulated differential equations are solved iteratively using an implicit difference scheme. In order to obtain a stable numerical solution, it is necessary to use appropriate steps of the time and spatial division. These were found by comparing the results obtained from the model with the results of the analytical solution available in the literature for the transient state, which constitutes the novelty of the present study. The accuracy of the results obtained from the model was verified experimentally by comparing the measured and the calculated history of the fluid temperature at the outlet of the collector. The calculation of the collector time constant is proposed in the paper as an example of the model practical application. The results of the time constant calculation were compared with the values obtained experimentally on the test stand. This is another novelty of the presented research. The analysed collector instantaneous efficiency was then calculated for selected outdoor conditions. The presented mathematical model can also be used to verify the correctness of the collector operation. Comparing, on an ongoing basis, the measured and the calculated values of the fluid temperature at the collector outlet, conclusions can be drawn about the process of solar glass fouling or glycol gelling. The model's simplicity and the low computational demands enable such comparisons in an online mode.

“…1,2 Although people have developed a series of green energy sources such as wind, nuclear and solar energy, the research and utilization of new energy sources has not yet reached the level of complete replacement of old energy sources. 3 Therefore, while actively discovering new energy sources, upgrading and optimizing energy-consuming industries to reduce energy consumption is another effective way to solve the current energy problem. The traditional separation technology in chemical production, energy production, noble gas enrichment, and carbon capture and sequestration is dominated by heat-driven separation, which consumes huge amounts of energy and is one of the areas in urgent need of improvement.…”

The recognition of climate change as real and unprecedented has been acknowledged by global communities. Furthermore, fossil fuel energy consumption and territorial emissions are identified as major drivers of climate change. Data collected from the World Bank for BRICS (Brazil, Russia, India, China, and South Africa) group of countries for the period from 1990 to 2018, and analyzed using Panel FGLS and Panel GEE models, revealed an inverted U-shaped relationship between GDP per capita and its square with fossil fuel energy consumption in BRICS countries. However, this relationship was not observed with territorial emissions. It is indicated that the BRICS group of countries is making efforts to reduce fossil fuel energy consumption, but investment in green technology is insufficient to reduce territorial emissions. Therefore, it is recommended that climate policies need to be more aggressively implemented to support investment in clean and green energy technology.
